GLSL::PtrProgram ACGDLLEXPORT ACG::SceneGraph::GLSL::loadComputeProgram	(	const char *	computeShaderFile,
		const GLSL::StringList *	macros = 0,
		bool	verbose = true
	)

load glsl compute shader and create GLSL program if successful

Shader file paths for this function are assumed to be relative to the "Shader" directory as specified in ShaderProgGenerator::getShaderDir()

	)

load shaders and create GLSL program if successful

Shader file paths for this function are assumed to be relative to the "Shader" directory as specified in ShaderProgGenerator::getShaderDir()

Definition at line 1082 of file GLSLShader.cc.

GLSL::StringList ACGDLLEXPORT ACG::SceneGraph::GLSL::loadShader	(	const char *	filename,
		const GLSL::StringList *	macros = 0,
		bool	appendNewLineChar = true,
		GLSL::StringList *	outIncludes = 0
	)

Loads the shader source.

The shader is assumed to be placed in ../shader relative to the executable's installation directory, if the path is a relative one. If it is determined that the path is absolute, the path is taken as is. Macros are inserted directly after the #version directive. According to glsl spec, only comments and white space are allowed before #version.

Parameters

filename	filename of shader
macros	[in] preprocessor macros (optional)
appendNewLineChar	should each string in the StringList end on a ' '
outIncludes	[out] additional files that were loaded to resolve #include directives.
